I own the leasehold on a two bedroom flat. A leak from the flat above has led to a buildings insurance claim. The builders started this morning and have found suspected asbestos. The removal of this, to complete the repair, is covered.

Asbestos was not mentioned in any documentation when I bought the property April 2006.

My question is what impact does this have on my ability to sell the flat and if the freeholder converted this flat in 1995 do I have any comeback to them ?

Thanks
